REFLECTOR FOR INCANDESCENT LAMPS.

SPECIFICATION forming part of Iletters Patent No. 305,200, datedSeptember 16, 1884.

Application filed October 22, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, PHILIP H. KLEIN, J r., of the city and State of NewYork, have in vented an Improvement in Reflectors for IncandescentLamps, of which the following is a specification.

Incandescent electric lamps have been applied upon chandeliers andbrackets with a reflector above the same. Such reflectors usually havealarge central opening. In consequence of the incandescent filament ofthe lamp being at some distance from the white reflecting surface thereis considerable light that is diffused and lost. This is especially thecase where the incandescent electriclamps are in streets or on theoutsides of buildings.

The object of my invention is to protect the incandescent lamps from theaction of rain or snow, and at the same time to largely intensify thelight from the same, and toconcentrate the rays from a group of lampsand render them better adapted to illuminating purposes.

In the drawings, Figure l is an inverted plan of the reflector andlamps; and Figs 2, 3, and 4 are sections of the reflectors of differentshapes, with theincandescent lamps applied thereto.

The reflector A is adapted to the place where it is to be'used. If it isfor a store or store-Window, or for a room, it will either be a flatdisk, or else an inverted cone or conoid, as shown in Fig. 2; but foroutside lamps the reflector should bea flattened cone or segment of aglobe, as represented in Figs. 3 and 4, so that water may drop from itsedges. The surfaces of the reflectors are preferably white. They may beenameled or otherwise .-coated, or they may be silvered. A dead \vhitesurface or a reflector made of porcelain or of opalescent glass isusually employed.

The peculiarity of my invention relates to the combination, with thereflector, of radially-diverging electric lamps placed parallel to thesurface of the reflector, or closely adjacent thereto, so that thelateral diffusion of the light is prevented and the rays directeddownwardly to obtain great illuminating power. The incandescent lamps BB are each of ordinary construction, the filament being within theexhausted glass vessel and connected to the conductors in the electriccircuit. The stems 00f these lamps are received into and supported by acentral hub or knob, D, which serves also to support the reflector A,and to contain the wires thatpass from the main conductors to therespective lamps. The lamps themselves are placed radially around thecentral knob, D, and they are in close proximity to the surface of thereflector, preferably parallel to the same, or nearly so,as

shown. In consequence of the incandescing filament being near to thereflecting-surface, such surfaceis highly luminous, and the power of thelamp is greatly increased. The lamps are proected by the reflectoragainst rain or snow and dust, and other foreign substances are keptfrom the lamp-glasses to a considerable extent.

I prefer to make the reflector air and water tight at the central knobor hub, D, for the better protection of the lamps and reflector; but Ido not limit myself in this particular, as there might be an openingbetween the hub D and the inner edge of the reflector.

I do not claim a series of electric lamps passing out from acentralsupport; neither do I claim a reflector above one or more lights, as thesame have been made use of.

I claim as my invention 1. The combinatiom-with a group ofincandescingelectric lamps, of a central hub, and

-a reflector connected to such hub and in close proximity above thelamps, the reflector being concave on the under side, so that the lampsare protected from injury and the light augmented, substantially asset'forth.

2. The combination, with a reflector, of a central hub or knobsupporting the same,

electric lamps connected with such hub and placed radially and inproximity to the re-' flector, and electric conductors passing to thelamps through such hub, substantially as set forth.

- Signed by me this 18th day of October, A.
